In this example,

  1. We create a num variable num1 with the value 4.
  2. We use the toString() method to get its string representation.
  3. We then print the result to standard output.

Dart Program

void main() {
  num num1 = 4;
  String stringValue = num1.toString();
  print('String representation of number: $stringValue');
}

Output

String representation of number: 4
